- INTERCHANGEABLE PANoRAMlG CAMERA.

sPEcIFIcATIoN forming part of Letters. Patent No. 691,020, dated January 14, 1902.

' Application filed December 13, 1900. Serial No. 39,587. (No model.)

To all whom it may concern.: f

Be it known that I, ROLLIN Hf TRUMBULL,

a citizen of the United States of America, re-

siding at Chicago, in the county of Cook and State of Illinois, have -invented certain new and useful Improvements in Interchangeable Panoramic Cameras, of which. the following is a specification. 1

My invention relatesto certain improvements in interchangeable panoramic cameras of the class in which means are provided for taking a panoramic view of thesurroundings of the cameras and also means for using the camera in the ordinary Way to photograph ments, and the essential characteristics of the improvements will be clearly defined in the claims.

In the drawings, Figure l is a perspective of a complete camera. Fig. 2 is a plan. of the interior of the camera withrthe case removed. Fig. 3 is 4a horizontal section inline 3 3 of-Fig. 6. Figa is a broken horizontal section in line 4 4 ofFig; 5.

tion of the parts seen in Fig. 2, with certain portions broken away, the View being in the direction indicated by the arrow 6 in said figure. Fig. 7 is a vertical section in line 7 7 of Fig. 3. Fig. Sis a rear elevation of theinner box of the camera. Fig. 9 is a broken vertical section in line 9 9 of Fig. 3. Fig. 10 is a horizontal section in line 10 l0 of Fig. 8, and Fig. 11 is a broken perspective of a swingingv nlm-covering door.

Looking at Fig. l, A is the cover or 'ease of the camera-box, supported upon legs a ct a2, at the top of Ywhich is a gear a3, fast to the .legs andV having an upwardly-projecting spindle 0,4, entering a tubular socket a5, furnishing a vertical pivot for the camera.

Looking now at Fig. 8, a pinion a6 is seen projecting from the lower portion of the camera-box, which is lettered A', said gear being Fig. 5 is a vertical section in line 5 5 of Fig. 4. Fig. 6 is a side eleva-l also shown in dotted lines in Fig. 3 as being fast upon a shaft' aflsecured to a frictionroller 0.8, bearing upon the film B. Said lm is carried by a spool B' and is wound upon a spool B2, passing from the' spool B', first between a fixed plate b and an adjustable swinging plate b2, pivoted at b3, (see dotted lines in Fig. 6,) and. preferably having at its free' end a roller b4. Between its ends two brackets b5, (see Fig. 6,) secured,respectively, at the top and bottomv of the case, are provided with adjusting-screws be, bearing upon the swinging plate to tighten it upon the ilm. This device furnishes a means for adjusting the tension upon the iilm to keep-the exposed surface taut.- From between `these tensionplates the lm passes around a roller 67, (see Fig. 3,) then across the back of the case and around a roller bs, and then over an idler b9 to the friction-roller as, from which it passes to theV winding-spool B2. The spindle of said spool is lettered B3 and extends through the top of the case, bearing upon its outer end a gearv c, kwhich forms a part of a train of gears c c' c2 c3 c4, the last two being secured upon. spindles c5 c6, provided with springs which may be wound up in the 'manner of ordinary clockwork, a fullA description of which is thought unnecessary. These gears are supported in a framework C, supported by posts C', secured to the case A and bearing elastic washers C2, preferably of rubber, to take u p any vibration of the clockwork. From the gears c3 c4 a second train of gears rotatesla regulating or governing spindle c7, (see Fig. 4,) said spindle bearing a friction and brake disk c8 and below the same a governing device ci), which may be of any well-known form-as, for instance, an ordinary escapement, a fan, or a centrifugal collar vhas. fast upon-it a notched stop-disk d4,

bear upon the brake-disk cg.

having a notch d5, (see Fig. 4,) adapted to receive when turned to the proper position the bent end e of a stop-lever E, pivoted vertically at e and provided with a second arm having the upwardly-bent end e2, adapted to A coiled spring e3 tends to press the end e2 against the brakedisk and does so whenever the end e drops into the notch d5. Upon the collar d3 is an outer collar d, having sufficient frictional engagement therewith to be rotated thereby and at the same time easily movable upon the same to enable it to be set in any desired position. This outer collar bears a cam 6X7, having a curved edge d8,'adapted to crowd the end of the stop-lever from the notch d5, and shoulders dg da, adapted to bear, respectively, upon pins db d@ in the notched disk to limit the angular movement of the cam upon said disk. When this disk is turned over the notch, it completes the contour of the disk and prevents the end of the stop-lever from entering said notch. Upon the upper portion of the outer collar is a dial-disk de and above the same an annular head df, by means of which the outer collar may be turned. When the cam is in the position seen in Fig. 4, exposing the notch, the dial-disk always has a position xed relatively to the notched disk, so that it affords means for determining at a glance the position of said notch.

Adjacent to the brake-disk as is a spindle f, extending from the top ot' the case and bearing outside of the same abutton F. 'Within the case it carries a brake-arm f', (see Fig. 4,) adapted to bear upon the brake-disk, and a crank-arm f2, to which is secured a cordfs,

passing over a pulley f4, Fig. 7, and secured to a slide f5, perforated at f6 to the size of the lens or largest shutter-opening and guided vertically in guides f7 f8. By turning the button F to bring the brake-arm upon the brake-disk the motion of the gear is stopped, checking the movement of the lilm and the rotation of the camera-box, and at the same time the slide f5 is drawn upward, shutting o the light from the lens and protecting the portion of the lm which happens to be exposed at that time. This enables the operation of the camera to be temporarily checked in case an object which is not desired to photograph appears upon the scene, and the camera need not be started again until the scene is in proper condition. A pair of springs f assist the downward movement ot' the slide. In the rear portion of the box, Figs. 3 and 10, is a vertical post g, upon which is secured a swinging door G, Fig. l1, which may be swung across the box to cover the film, as seen in Figs. lO and 3, or may be swung along pal'- allel with one of the partitions fr, as seen in dotted lines in Fig. 3. The post gis provided with a iiat spring-arm' g', perforated at g2, and pins g3 are provided upon the bottom of the case to enter-the perforation and hold the arm in the desired positions. Upon the opposite side of the box is a similar post IAI, having a similar arm 71l to swing around and engage the edge of the swinging door when the same is placed in front of the iilrn. The door G is vertically slotted at g, and a slide g5 is mounted in guides Q6 and moved horizontally by means of bell-crank levers g7 gs, pivoted to the slide at g9 g and to the door by means of pivots gb g, extending through slots gd ge in the slide. The two bell-crank levers are connected by a bar gf, guided in brackets gh gi, secured to the door. The slide affords means of adjustingthe width of the slot, and consequently the extent of the exposure of the film as it moves past the slot. Back of the film is pivoted a plate K upon a post 7a, extending through the top of the case and bearing an arm 7c', connected to a spring k2, tending to draw the arm so as to crowd the plate against the back of the iilm and hold the latter tightly against the slotted portion of the door.

The various portions of my invention are in certain respects independent of the exact form or 'arrangement and may be used together or separately, as is thought desirable.

I claim as new and desire to secure by Letters Patentl. In a rotatable camera, the combination with a rotating camera-box, of clockwork for rotating the same, supported by the box and separated therefrom by elastic washers to take up any vibration of the clockwork; substantially as described.
